Berserk gay

She knows what love looks like. He also reasserted dominance when he violated Casca while Guts watched. With Guts it's because he was able gain enough strength and skill to challenge both Zodd and the apostles while still remaining human (barring the the use of the Dragon Slayer sword and the Berserk armor). It's implied Zod admires his spiritual strength along with his martial prowess.

It is amazingly creepy.

There's also why Guts left in the first place. However, before turning into Femto when he’s commenting on how he feels about Guts he says “Of all the thousands of comrades and enemies, only you and you alone made me forget my dream.” As soon as he sees Guts face, he gives him a sad smile before performing the sacrifice necessary to become Femto while Guts tries desperately to reach him.

And then there's when Guts and the Hawks discover Griffith broken and tortured body, Guts cries while holding him and then goes...

Casca complained, saying she's a warrior and that it doesn't suit her, but Danann insisted on it, saying it's perfect, that she looks beautiful, and that she also looks like a 'dark elf princess'. However, those who stop to think about it soon realize that the answer is much more complicated than a simple yes or no question. Even Guts might be bi, to be honest; that scene of him playing with a naked Griffith and tossing water on one another must have gotten Guts quite wet, if you know what I mean.

Thoughts?

It's more commonly translated as "fag boy".
In the movie Guts says, "you can have anything, my sword or my ass." Again, not very subtle.
- The more Squicky bit of Ho Yay has to be when Griffith comments on his many, many conflicting feelings for Guts, moments before sacrificing his men to the Godhand, turning into a demon, and then raping Casca, his love interest, which was all most likely done purely out of spite that Guts and Casca tried to leave him.
  
  In the movie in particular much emphasis is put on his gaze when he sees Guts after a year of torture like he’s in awe of him.
- It's especially interesting to note that Guts Hates Being Touched except by his Love Interest Casca (and even with her, Guts was triggered the first time they touched), and yet he didn't seem to mind when Griffith held his face in his hands, got really close following their first duel, looked into his eyes, and said "You belong to me now, Guts” even though the two had just recently met.
- If you go by Freudian imagery there's also the part during their first fight where Guts put Griffith's sword in his mouth.
Also, Griffith trusted Guts with the seedier elements of his power plays and opened up to him more than anyone, even Casca.
Adding to the tension between Guts and Griffith is what happened after the Eclipse, when Griffith comes back to create his new army and build his kingdom on earth.

Also, despite his denial, Zodd deeply respects Guts and is extremely fond of fighting with or against him. He tells Guts that he just wanted see if feelings once again surfaced in his presence, and was happy that they no longer did.
And then there's the manga-only scene in the library where Griffith is reading what appears to be the Kama Sutra and offers to lend it to Guts.
Or before Guts and the Band Of The Hawk rescue Griffith after his year long torture Griffith is shown thinking about all his feelings of hate, indignation, friendship, sorrow, and affection towards Guts.

Intrigued, and unfamiliar with what "bara" even meant, I decided to look into it -- and I was shocked at my findings.

Here, you can clearly see the bara Guts' man boobs jiggle as he lands on the ground.

This is a rather groundbreaking discovery.
Now I question the heterosexuality of Berserk, and I must conclude that it is indeed quite gay -- not that there's anything wrong with that.

But it doesn't end there:
I realized that the sheer gayness of Berserk was in front of me the entire time.

Thanks!

In doing so, he also jeopardized the dream he'd been working on for so long.

Griffith's relationship with Guts could also be one of establishing dominance, at least as it progressed.

Following his rebirth into the physical world, several male characters describe how just hearing his voice makes them feel strange things.

Owen and Laban, who are Heterosexual Life-Partners, have a Stupid Sexy Flanders moment towards Griffith, and late in the volumes are overjoyed to find each other again after a long separation.

This is why they find it surprising when he goes out of his way to give Guts special treatment. It's reasonable to assume Griffith thought of Guts as more than a friend, even if nothing was explicitly stated.
